Sparrows, Problem Solving and Collective Intelligence
April 29, 2009 by sean.
Researchers at the University of Pannonia, Hungary demonstrate how sparrrows solve problems more quickly as a group than as individuals [via scienceblogs]:
Liker and Bokony’s sparrow experiments are the first to show that large animal groups outperform smaller ones at problem-solving tasks where they have to invent new techniques. House sparrows are a good choice for a study like this. They are very social birds that live in flocks of anywhere from a few individuals to a few hundred. They are opportunists that use their relatively large brains to find food in all sorts of new environments.

When It Comes to Intelligence, Does Brain Size Matter?
April 15, 2009 by sean.
“That may be so, however, new scientific studies across several animal species, including humans, are challenging the notion that brain size alone is a measure of intelligence. Rather, scientists now argue, it is a brain’s underlying organization and molecular activity at its synapses (the communication junctions between neurons through which nerve impulses pass) that dictate intelligence.” [via Scientific American]
